Local Bubble

About

  • The Local Bubble is a 1,000-light-year-wide cavity or a superbubble in an interstellar medium. Local bubble also exists in the Milky Way.
  • The Local Bubble is not spherical, but seems to be narrower in the galactic plane, becoming elliptical, and may widen above and below the galactic plane, taking the shape of an hourglass.
  • Formation: Local Bubble is thought to have originated from supernovae roughly 14 million years ago.
  • Significance: Superbubbles trigger the formation of new stars and planets and influence the overall shapes of galaxies.
    • Studies have shown that star-forming regions occur along the surface of bubbles due to accumulation of gases and debris.
  • Despite their discovery, mechanisms powering the formation and expansion of local bubbles are not known. The role played by magnetic fields in their formation is also not known.

Exoplanets

Context: The National Aeronautics and Space Administration (NASA) has announced that the James Webb Space Telescope has discovered its first new exoplanet.

About Exoplanets

Exoplanets
Exoplanets
  • Exoplanets are planets that orbit other stars and are beyond our solar system.
  • Exoplanets come in a host of different sizes and are known to have different kinds of temperatures.
  • Also, they are made up of elements similar to those of the planets in our solar system, but the mixture of those elements may differ.
  • The new discovery: Researchers have labelled the recently discovered planet as LHS 475 b, and it’s roughly the same size as Earth.
    • Located just 41 light-years away, the planet orbits very close to a red dwarf star and completes a full orbit in just two days.
  • Significance: The study about exoplanets not only broadens our understanding of other solar systems, but also helps us piece together information about our own planetary system and origin.
  • Discovering exoplanets is quite tough as they are small and hard to spot around their bright host stars. So, scientists rely on the transit method, which is “measuring the dimming of a star that happens to have a planet pass in front of it”.
  • Need for Studying Exoplanets
    • To find answers if we are alone in the Universe.
    • To determine if a discovered world is habitable or not.

 

Hockey Blue Turf

About Blue Turf

  • It was first introduced in the 2012 London Olympics, alongside a fluorescent yellow ball.
  • Wet playing surface: Water reduces friction and improves the speed and consistency of the ball roll, allowing for smooth, fast play.

  • Significance: Blue surface provides outstanding contrast against the yellow ball.
    • It helps players spot and control the ball better.
    • Excellent foot grip and fewer skin burns
    • Uniform ball roll
    • High ball accuracy and roll speed
    • Lower friction in either wet or dry weather
    • Fine shock-absorbing ability
    • Tough and elastic fibres
  • Boon for broadcasters: Contrast between the deep blue of the field and the yellow of the ball makes the game easier to follow, when compared with the traditional green surface and white ball.
  • Develop Dedicated Viewership and Fandom: Improve fan interest by providing field hockey with one of the most unique playing surfaces in sports.
